2019-nCoV qRT-PCR Detection Assay
Expedite your research into the 2019 novel coronavirus
With the first case of China-linked coronavirus reported in US on Jan. 21st, 2020, this new pneumonia-like virus called 2019 Novel Coronavirus (2019-nCoV) is gaining global attention. The outbreak began in Wuhan, China at the end of 2019. As of Jan. 22nd, 2020, 2019-nCoV has killed 17 people, with 509 confirmed cases in China.
In response to 2019-nCoV epidemic, GenScript announced today that all 2019-nCoV gene orders of Rush Gene Synthesis will be treated with the highest priority, following an announcement on Jan. 21st, 2020 that it offers free real-time reverse-transcription polymerase chain reaction (rRT-PCR) reagent samples in China for laboratory diagnostic testing.
"GenScript fully supports the development of diagnostics, therapeutics and vaccine. We promise that we will deliver all projects for 2019-nCoV epidemic as the top priority," said President of Life Science Group, Sherry Shao.

Here are four things you should know about a coronavirus:
What is a coronavirus?
How does it spread?
Coronaviruses normally circulate among animals, but can be transmitted from animals to people in rare cases. The initial reported cases of the current outbreak in Wuhan, China are closely linked to a large seafood and animal market, suggesting animal-to-people spread. However now it has been confirmed by Chinese officials that there is "definitely human-to-human transmission", which suggests higher chances of introduction of the novel virus.
How to prevent and treat?
There are no specific medicine or vaccine available now targeting human coronaviruses. Several teams of scientists in United States and China are developing vaccines for the novel virus, including vaccine biotechnology companies. Novavax, Inc. (NASDAQ: NVAX) announced Tuesday afternoon it has initiated development of a vaccine candidate in response to the first confirmed Wuhan coronavirus case in USA.
Chinese authority has identified the novel Wuhan coronavirus via next generation sequencing (NGS) from cultured virus or directly from samples of patients. On Jan 12th, China officially shared full genetic sequence data with World Health Organization (WHO) and on the GISAID platform. The data is of great importance of developing PCR test kits and WHO subsequently released interim guide for laboratory testing in suspected human cases.
Coronaviruses are named by their characteristic royal crown like surface under electron microscopy. While proteins contribute to the crown like envelope and projecting spikes around it, the viruses depend on their single stranded RNA genome to replicate in the host cell. It is still unclear how exactly the viruses get into the host cell.
There are currently seven identified coronaviruses which can infect people according to the US Centers for Disease Control and Prevention (CDC). The virus associated with the latest confirmed case in United States is determined as a novel type of coronavirus, 2019 Novel Coronavirus (2019-nCoV), also referred as the "Wuhan coronavirus".
